Add CTRL +/- and CTRL scroll shortcuts to increase/decrease serial/network monitor output text size. This font size is shared with the editor and adjusting either will update both.
Partially fixes#8615
`EditorTab.setText()` now already preserves the caret position. The code
used during auto-format tried a bit harder to preserve the position
correctly, and probably worked better in a few specific cases, but for
most cases they would both end up approximating the caret position
anyway. To make the code simpler, better just stick to the simpler
approach.
When completely replacing all text, all highlights will end up at the
start of the file. Since keeping them at the right place is tricky (even
impossible in some circumstances), just remove them now.
This already happened in the autoformat code, so that part can be
removed.
Now that each file in the sketch has its own text area in the GUI, it is
no longer needed to store the (possibly modified) contents of each file
inside SketchCode. Keeping the contents in the text area is sufficient.
Doing so allows removing the code that dealt with copying contents from
the text area into the SketchCode instance at the right time, which was
fragile and messy.
However, when compiling a sketch, the current (modified) file contents
still should be used. To allow this, the TextStorage interface is
introduced. This is a simple interface implemented by EditorTab, that
allows the SketchCode class to query the GUI for the current contents.
By using an interface, there is no direct dependency on the GUI code. If
no TextStorage instance is attached to a SketchCode, it will just assume
that the contents are always unmodified and the contents from the file
will be used during compilation.
When not using the GUI (e.g. just compiling something from the
commandline), there is no need to load the file contents from disk at
all, the filenames just have to be passed to arduino-builder and the
compiler. So, the SketchCode constructor no longer calls its `load()`
function, leaving this to the GUI code to call when appropriate. This
also modifies the `SketchCode.load()` function to return the loaded
text, instead of storing it internally.
To still support adding new files to a sketch (whose file does not
exist on disk yet), the EditorTab constructor now allows an initial
contents to be passed in, to be used instead of loading from disk. Only
the empty string is passed for new files now, but this could also be
used for the bare minimum contents of a new sketch later (which is now
down by creating a .ino file in a temporary directory).
Another side effect of this change is that all changes to the contents
now happen through the text area, which keeps track of modifications
already. This allows removing all manual calls to `Sketch.setModified()`
(even more, the entire function is removed, making `Sketch.isModified()`
always check the modification status of the contained files).
RSyntaxTextArea appears to support using a single instance and replacing
the underlying text and document when switching between tabs, but in
practice this support is not complete and even though the
RSyntaxTextArea developers did some work to improve the situation, they
recommend to just use a seperate instance for each tab.
This commit implements exactly that. A new class EditorTab is introduce
to wrap the RSyntaxTextArea and containing scroll pane, and to
encapsulate the code related to handling the text area itself. Doing so
removes some quirks and prepares for some later additions. In
particular, error highlights are now no longer shared between all tabs,
which was previously the case.
This commit mostly moves code from Editor into EditorTab, and updates
the callers to use getCurrentTab() and call methods on the result
instead of calling them on Editor. Some code is added to take care of
creating multiple EditorTab objects and switching between them. Some
small changes have been made to make the flow of opening files work,
though these are mostly a bit hacky.
While moving code, changes to the rest of the code were kept minimal,
retaining existing interfaces as much as possible. This sometimes result
in less than ideal code, which should be cleaned up in subsequent
commits.
The SketchCodeDocument class has been pretty much emptied out, since
it was mostly used to store things for tabs in the background, which are
now just stored in each RSyntaxTextArea separately. The last remaining
bits of this class can probably be moved or implemented differently
later, so it can be removed.
The entire flow of working with sketches and files needs to be cleaned
up next, so no thorough attempt at testing this commit was done. It is
likely that there are plenty of corner cases and race conditions, which
will be fixed once the reset of the code is cleaned up.
Fixes#3441
